HomeServicesPlat of Subdivision › Blue Island, IL

Blue Island is an older river-and-rail city on the Cal-Sag corridor, mixing historic neighborhoods, an industrial waterfront, and established commercial streets. Given its long development history, a plat of subdivision here commonly supports splitting a larger parcel, re-platting an industrial or riverfront site, or clearing the way for redevelopment. Broad new subdivisions of undeveloped land are uncommon in a city with this much existing fabric.

What a plat of subdivision does

A plat of subdivision divides a parcel into lots, blocks, streets and easements in compliance with the municipality’s subdivision and zoning ordinances, then is recorded with the county. It is the foundation of any residential or commercial development.

Blue Island & Cook County specifics

Blue Island has around 22,500 residents and spans the Calumet, Worth, Bremen, and Thornton townships in southern Cook County, sitting along the Cal-Sag Channel. Its varied township footprint and waterfront setting mean surveyors often deal with easements, drainage, and existing rights-of-way when platting. A plat of subdivision must comply with the city’s subdivision and zoning ordinances before approval, and it is then recorded with the Cook County Clerk’s Recordings Division, which took over the Recorder of Deeds function in December 2020. That recording establishes each new lot for title, financing, and permitting purposes.
